SANITARY MILK-FOTTLE CLOSURE.

This invention relates to a combined sani-' tary closure and drinking cup for bottles, jars, etc., and has for one of its objects the provision of a device for efliciently embrac-" 'ing the entire mouth of a receptacle to form a sanitary closure therefor to prevent the accumulation of germs and foreign matter upon the surrounding edge of the receptacle,

and at the same time provide an efficient sanitary drinking cup.

A further object of this invention resides in the provision of a closure to be used in combination with a bottle, jar or other receptacle having a specifically constructed neck for receiving the closure,'in con unction with means for securing the closure upon the neck of the receptacle which is capable of ready adjustment upon the'neck of the receptacle to provide for the efficient application or removal of the cup and closure to and from the receptacle.

A still further object of this invention resides in the provision of a combined sanitary closure and drinking cup for receptacles formed of a flat piece of parafiin paper or other suitable materialthat is impervious to fluids and folded to form a closure for the receptacle and at the same time capable of use as a sanitary drinking cup when. reg

'moved from the receptacle.

And' a still further object of this invention resides in the provision of a combined closure and drinking cup for bottles, jars and other receptacles formed of flat pieces of impervious material which canebe readily shipped, occuying little space and which can also be readily folded into shape for a sanitary closure for hermetically sealing the receptacle and also capable of use as adrinking cupthe saine being. eflicient and durable in purpose, simple in construction, and which can be manufactured and sold upon the market at a nominal cost.

any

with the annular groove.10 formed by indenting that portion thereof inwardly to be hereinafter more fully explained.

The combined closure and cup is formed from a blank or disk 11 shown in Fig. 3, the

blank being cut from a piece of thick parafiin paper or any other suitable impervious material or circular formation excepting certain portions of the periphery of the blank or disk 11 is cut with straight edges as shown at 12, and adjacent the edges of the straight edges 12, the blank or disk 11 is indented to form the grooves 13 which grooves form the continudus groove 10 of the closure and cup when the same is folded for this purpose. The blank or disk 11 is provided with the central circular crease 14 and the straight creases 15 radiating therefrom to the periphery of the blank or disk 11, thus dividing the blank or disk 11 into opposing segments 16, 16; 17, 17; 18, 18 and 19, 19; and to fold the blank or disk 11 to shape or form the closure and cup, the segments 19, 19 are folded upwardly and inwardly toward each other for a distance at a portion of the crease 14:, the segments 17, 17 are then folded upon the segments 16,16, and thereafter the segments 18, 18 are folded upon the segments 16, 16 and 17, 17, whereby that portion within the scored or creased line 14 forms the bottom 7 of the closure and cup, the segments 19, 19 now assume a circular form and provide the circular wall 8 of the closure and cup, the respective ends of the grooves 13 are brought into registration with each other and form the annular circular groove 10 of the closure and cup, it is, of course, understood that the segments 16, 16

.are bent and folded upwardly and inwardly toward each other along the remaining portion of the crease l4 and that the segments 17, 17 and 18, 18 are bent along the respective creases or scored lines 15.

In Fig. 4 the closure and cup are shown as provided with the stopper 20 secured to the bottom 7 within the closure and cup, the stopper being designed to fit snugly within the mouth 6 of the receptacle and may be formed of cork, rubber or any other suitable material, while the view shown in Fig. 5 shows a portion of the bottom 7 being indented inwardly as at 21 in order that the indented portion 21 will pass for a distance into the mouth of the receptacle and is designed for use in lieu of the vstopper 20 as shown in Fig. 4. a

In applying the combined closure and cup upon the neck 2 of the receptacle, the same is inverted and passed over the neck 2 until the edge of the mouth 6 of the receptacle engages the inner side of the bottom 7, the wall 8 of the cup snugly embracing the exterior of the neck 2 and the annular groove 10 of the closure and cup being seated within the groove 4 of the neck 2,

and for securing the closure and cup upon the neck 2 the circular ring member 22 is provided, the ring member 22 being formed of coil spring wire or rubber, preferably rubber, is then passed over the closure and cup until the ring member 22 isseated within the groove 10 of the closure and cup, the ring member 22 being elastic presses the grooved edge of the closure and cup firmly into the groove 4 of the neck 2 of the receptacle. lVhen it is desired to remove the closure, it is only necessary to force the ring member 22 downwardly until the same is seated in the groove 3 of the neck 2, whereupon the closure may be removed and the contents of the receptacle poured therein, the closure then performing the function of a drinking cup and after such use the same is discarded and a new blank folded as before described into the shape of a cup, and thereafter passed over the neck 2 in the manner as before described, the ring member 22 being then forced upwardly out of the groove 3 and over the grooved edge 10 of the closure and cup thus securing the grooved edge 10 firmly within the groove 4 for again closing the receptacle.

From the foregoing, it is obvious that we have invented a most efiicient combined sanitary closure and cup for use in conjunction with a specifically formed receptacle for holding fluid such as milk, mineral water, beverages or other fluids which is cheap, strictly sanitary from the fact that the same entirely embraces and covers every portion of the mouth of the bottle whereby it is free from germs and foreign matter which may collect thereon, as well as useful as a drinking cup, and which invention now fills a long felt want.

It is tobe further understood that while we have here shown and describedthe combined closure and drinking cup as of circular formation, the same may be formed of any desired configuration, this being accomplished by the manner of creasing or scoring the-blank or disk 11 together with the formation of the neck 2.0f the receptacle 1, and we do not wish it to be understood that we are limiting ourselves to the. circular formation of our device as the same what we claim as new and desire to secure" by Letters Patent is 1. The combination with a fluid receptacle, an upwardly and inwardly tapered neck same, an annular therefor, spaced parallel annular grooves formed in the lower exterior surfaces of said neck, of a combined closure and cup formed of impervious material and tapered to conform to said neck for snugly embracing the groove formed adjacent the edge of said closure and in the uppermost of said grooves of said neck, and a resilient ring for encircling said neck for seating within the groove of said closure and cup within the uppermost groove of said neck for retainin said closure and cup upon the neck of said receptacle,'said resilient ring adapted to be seated in the lowermost of said grooves of said neck when removing said closure and cup from said neck.

2. The combination with a fluid receptacle having a tapered neck provided with spaced annular grooves, closure and cup therefor, said closure and cup formed of a fiat blank of impervious material provided with a centrally disposed circularly. creased portion to provide a bottom therefor, creased lines extending radicup for seating said closure .upon

of a combined ally from the circular creased portion, and obliquely disposed creased lines intersecting the circular creased portion at the point of the intersection of the radially disposed creased lines whereby to provide overlapping segments to form the side walls of the said closure and cup, said blank being also provided with marginal indentations to provide an annular groove adjacent the edge of said closure and cup when said blank has been bent to form the same, the annular groove of said closure adapted to be seated in one of the grooves of said neck, and a resilient ring adapted to be seated in said annular groove of said closure for retaining the neck of the receptacle In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.v
